WiNDQW OR LIKE SCREEN.

Patented July 17, 1906.

Application filed January 27,1906. Serial Kai 198,199.

To all 10. mm it may concern:

Be it known that I, Cnannns C. ARM- STRONG, a citizen of the United States, residing at Marysville, Ohio, have invented certain new and useful Improvements in indow or Like Screens, of which the following is a specification.

My invention relates to windowscreens in which the frame is composed, preferably, of metal strips, though it will be understood that I do not limit myself to this material.

One object of my invention is to provide a window-screen in which the wire fabric will be stretched in the act of clamping it in place and without danger of rupturing the strands of which the fabric is composed.

A further object of my invention is to provide such a construction of window-screen as will permit the user or householder to readily renew the screen fabric or cloth himself, the frame. being of such arrangement and construction that a person of ordinary intelligence and skill can release the clamp ing members, apply the screen cloth or fabric in proper position in relation thereto, and then by simply bringing the clamping members together effect the stretching of the cloth and the holding or clamping of the same in place.

In constructing the clamping or holding members I have sought to avoid subjecting the screen material to sharp edges or angular bends, which tend to break the strands of Y which the screen fabric is composed.

The invention consists in the features and combination and arrangement of arts hereinafter described, and particular y pointed.

out in the claims.

In the accompanying drawings, Figure 1 is a front or outside face view of-a windowscreen embodying my improvements. Fig. 2 is a sectional view on the line 2 2 of Fig. 1. Fig. 3 is a front view of a part of the screen, showing the inside face thereof. Fig. 4 is a view similar to Fig. i with parts broken away and parts omitted and with the movable clamping members thrown up slightly from their clamping position for the insertion or removal of the screen fabric. Fig. 5 is a detail sectional view on line 5 5 of Fig. 1. Fig. 6 is a detail sectional view on line 6 6 of Fig. 1. Fig. 7 is a sectional view of a modification; in which the frame member is made of wood or like material.

The screen-frame is composed of the frame members 1, rigidly attached to each other by corner-pieces by means of eyelets or rivets 3, as will be hereinafter more particularly referred to. The members 1 are on the inside face of the frame, and they have associated therewith movable members 4, coextensive therewith and between which andthe members or strips 1 the screen cloth or fabric 5 is held. There is one pair of these strips or members 1 e for each side of the rectangle of the frame, and the companion strips, or those which operate in connection with each other, are connected pivotally together. to form this pivotal connection by providing a curved portion 6, on the member 1, struck on the arc of a circle, which receives within it a concentric curved portion 7 of the companion member 4. This allows the member 4 to be turned or tipped up, as shown on the right of Fig. 2, in relation to its com anion member 1, so that the screen clot or I prefer fabric can be introduced between the said companion members. This tipped up'or open osition of the clamping members is also il ustrated in Fig. 4, where each of the four sides of the frame may be said to be open ready to receive the screen-cloth, be-

cause each of the movable clamping members 4 is swung upwardly in relation to its companion member 1. This rolling or curving of the edges of the clamping members not onlyprovides a simple form of pivotal connection between them, but it forms a rolled edge for each one of the members, which serves to give all the strength and rigidity necessary in a frame of this character.

Each ofthe clampin members 1 and 4 is provided on its inner edge with arolled portion, (marked, respectively, 1 and 4 and each is provided intermediate of its width with an inwardly-projecting rib orbea'd 8, arranged to be positioned directly op osite to each other when the clamping mem ers are in their closed or clamped position.

It will be seen from Fig. 2 that the clamping member e for the outer face of the frame is narrower in width than the clamping memher 1, and this difference in width of the two members brings the rolled edge 4 of the inbvable member slightly within the inner face of the rolled edge 1 of the member 1 when the parts are in closed osition, as shown on the left of Fig. 2 and a so of Fig. 5.

It will be readily seen'that when the screen fabric or cloth is placed in position within the frame with its edges passing between the upturned clamping members 4 and the fixed members 1, as shown on the right of Fig. 2, the simple act of pressing down the members 4 into their closed position, as shown on the left of Fig. 2 and in Fig. 5, will cause the fabric to be stretched by drawing it over the rolled edge 1*, and the final pressure in bringing the clamping members into closed position will grip or clamp the fabric between the ribs 8 on the opposing clamping members after the said fabric has been drawn and stretched by the action of the rolled edges 1 and a.

it will be further noticed that the stretching or drawing of the screen fabric being done by the rounded or rolled edge 4* cooperating with the rounded edge 1 all liability of rupturing the fabric will be avoided. No shar angles are turned by the fabric, nor is it subjected to pressure by sharp edges. The ribs 8 are rounded on their contact-faces, so as not to damage the screen or impair its strength. The holding effect, it will be understood, is not only derived from the grip of heads 8, but also from the contact of the rolled edge 4 with the screen-cloth operating in connection with the rolled edge 1, it being noted from Fig. 5 that the screencloth is depressed by the rolled edge 43 below the point of contact of the ribs 8 therewith.

In order to hold the clamping members securely in lace, I. employ screws 10, assing through t e movable clamping mem er, as shown in Fig. 5and also in Fig. 1, and throu h screw-threaded eyelets 11, inserted in the clamping member or stri 1. These screws are provided with enlarge heads 12, and their ends are pointed, as at 13, so as to enter the meshes of the fabric and spread the same "without breaking the strands. I also employ corner pieces or clamps 14 for the outer face of the frame, and these clamps are of a width to make their inner edges flush with the inner edges of the movable clamping member, as shown in Fig. 1. The outer edges of the corner-pieces are curved to conform to the outer edges 6 of the members 1, and, as shown in Fig. 2, the corner-clamping members 14 have their outer edges meeting the outer edgos of the fixed corner clamps or lates 2 above referred to, the meeting-point lir ng midway of the thickness of the screen. Each of the corner clamps or members, as shown in Fig. 2, is ribbed at 15 to fit into the ribs of the clamping members 1 and 4, and the inner edge of the corner-clamp 2 is extended to a point within and in contact with the-rolled edge 1", as at 16 in Fig. 2.

The (wrnorrlamps or plates 1 4 forthcoutcr face of the frame are removably hold in place by the screws 17, similar to those above dor-ribod, which pass through the said corner- (damps. the clamping mmnbors 4. and into iho threaded ferrules or eyelets 3 above referred to, which are rigidly secured to the clamping member 1 and its corner-plain .2.

opened, so t In order to remove the screening material, it is simply necessary to remove the screws 17, whereupon the corner-clamps 14 may be removed, and then by removing the screws 12 the clampin members 4 may be tipped up or %at the screen-cloth can be disengaged from all sides at once and a new cloth may be inserted, and this will be held by the reverse of the operation above mentioned.

The eyelets 3 are held in place by simply upsetting a portion of their inner edge into. contact with the inner side of the clamping members 1.

iv provide finger-pieces or lifting-rings 18, attached to the clamping members 2 on the inner side of the frame.

S rings 19 are arran ed at the side edges of tile frame, which are eld by their ends being clamped in a recess of the clamping strip or member 1 by means of an overlapping portion 20 of the corner clamps or plates.

A material feature of advantage in my construction is that the rolled or curved edges of the clamping members in pivotal connection not only permit the movable member to be tippedup easily and freely in relation to the other, but the parts being in frictional contact at the said pivot the movable member will be held in its open position, so that the frame throughout its extent will be open for the ready insertion and adjustment of the screen-cloth thereto.

It will be understood that, except as specifically mentioned in the claims, I do not wish to limit myself to the details of construction. For instance, I may dispense with the eyelets and instead have the screws enter threaded openings in the frame member itself.

Instead of em loying frame or clamping members made ofmetal, I may, as shown in Fig. 7, make the clamping members differentlythat is, for instance, the member 1 may be made of wood having a groove or socket 6 to receiye the rounded orrolled edge 7 of the clamping member 4. The wooden member has the rounded inner ed e 1, cooperating with the rolled edge 4* of t e member 4 in a manner similar to that above described to stretch and hold the screen-cloth. This form of screen also has the opposing ribs for gripping the screen-cloth, and the members are held together b means of a screw.

In both forms 0 the invention the clamping members are pivotally connected or hinged together.

I claim as my invention- 1. In combination in a window-screen, a frame comprising clamping members extending along one side thereof, one of said members having a channel and the outer edge of the. other member having its edge turning in said channel, the said members clam ing the fabric between their inner edges and means for holding the members in clamping'relation.
